H2S Analyzer for Liquids for Continuous Hydrogen Sulfide Measurement in Process Streams

The Model 205 PermaStream is an advanced H2S analyzer for liquids designed to deliver accurate, real-time measurement in hydrocarbon and water streams. For full product specifications, refer to the Model 205 PermaStream analyzer page. This system uses membrane-based extraction to separate H₂S from the liquid phase, enabling precise gas-phase detection without the complexity of traditional systems. By delivering stable, repeatable results, it allows operators to maintain confidence in safety, compliance, and process control measurements.

Advanced Membrane Extraction for Accurate H2S Measurement

Unlike conventional headspace stripping systems, this analyzer utilizes proprietary membrane technology to efficiently extract hydrogen sulfide into a clean gas stream. This approach removes the need for complex sample conditioning, filters, and frequent maintenance while ensuring accurate readings without cross-interference.

For applications requiring hydrocarbon monitoring in liquid systems, solutions such as the VOC Analyzer for Water (Model 204 PermaStream) provide a complementary measurement for detecting hydrocarbon contamination alongside H2S.

Real-Time Process Control with Liquid-Phase H2S Measurement

With rapid measurement capability, the Model 205 PermaStream enables responsive process control and continuous visibility into changing process conditions. It operates directly at process pressure, flow, and temperature, ensuring representative sampling without delays. This allows operators to reduce chemical overdosing, prevent false alarms, and maintain optimal operating conditions.

Integrated Measurement Across Gas and Liquid Phases

In facilities where both gas and liquid phase monitoring is required, complementary solutions such as the H2S Gas Analyzer provide a complete hydrogen sulfide measurement strategy across the process.

Low-Maintenance Design for Long-Term Operation

The Model 205 PermaStream eliminates common failure points associated with traditional analyzers. With no moving parts, no required field calibration, and no sample conditioning components, it significantly reduces maintenance requirements and downtime. Its robust design protects the sensor while delivering consistent, drift-free performance across a wide measurement range.
